I use LibreOffice 18.104.22.168 (an English version with English menus, help, etc) on CentOS6 to edit a document in Russian.
I downloaded a Russian Dictionary pack “made by the AOT group” to spellcheck (which it did right) and hyphenate my document (did that right too).
Next I decided to change the font size, and my hyphens remained where they were, jumping all over the document in the middle of almost every line. Hardly the correct behaviour.
Should I understand that this is a problem with LibreOffice, or just with that particular dictionary?
Is there something I could (should) have made to have the feature work as intended, that is: (just in case the authors do not know) to continuously check and redo hyphenation every time I decide to change one paragraph, or even one single word?
